Description

液体蒸发元件
技术领域
本发明涉及液体蒸发元件，特别是水溶液蒸发元件，所述水溶液可包含芳香物质，比如咖啡因、尼古丁和其它物质，所述水溶液优选用于蒸发液的吸入。
背景技术
用于加热含有芳香物质(例如精油或类似物)的液体的装置早已为人们所知，人们使用这类装置的目的是为了吸入充满芳香物质的液体蒸汽。
蒸发液体吸入物的医药用途在于，例如，吸入精油用于减轻感冒症状和呼吸道疾病。另一个用途在于尼古丁的施用，如专利文献DE 10 2004 033 579 B4所述。在该专利文献中，水、尼古丁和芳香物质的混合物被蒸发，其中所述芳香物质在相对较低的温度即50～90℃时已被蒸发。尼古丁本身只在大约300℃蒸发，但尼古丁吸湿并可承受蒸馏过程。因此存在一种可能性，即：尼古丁-水的均匀混合物早已在相对较低的温度下蒸发。通过尼古丁/香味/蒸汽混合物的上升，而与此同时没有致癌物质上升(这些致癌物质主要是冷凝了)，随着尼古丁通过吸烟上升，这种形式的尼古丁上升开发了用于尼古丁享乐的可能性，该可能性即：人们可以吸入理想剂量的尼古丁，而与此同时又不会吸入致癌物质，也不会对周围人等产生不利影响。
专利文献DE 10 2004 033 579 B4公开了一种方法，即：用蒸发溶液充满多孔陶瓷材料，然后通过加热陶瓷元件来释放蒸汽，以用于吸入。在该文献中，可用电子热源或外部热源(如打火机或类似物)作热源用于加热。但是，如果能量需求很高的话，则只能采用比较重、体积大的电池来作电热源。特别是对于轻便式的吸入装置而言，这种电池不实际，太重也太贵。
外部热源，比如打火机或类似物，可能损害和弄脏吸入装置，因为它们有非常高的火焰温度，且因此非常不具有用户友好性。此外，持有明火在许多方面也意味着危险，且不受欢迎，因为会形成燃烧产物。
EP 0 371 282 A公开了一种气溶胶蒸发装置，该装置包括热源和蓄水器，该热源不基于燃烧作用，而是例如含有氧化钙的热源，其与水接触即产生热；所述蓄水器与所述热源相分离但有热接触，用于待加热的气溶胶。
发明内容
因此本发明的目的是提供一种液体蒸发元件，该蒸发元件结构紧凑、便宜且具有多种用途，特别是可用于吸入目的。
为了实现上述目的，本发明提供一种用于蒸发液体、特别是水溶液的蒸发元件，该蒸发元件包括第一蓄水器、第二蓄水器和开口元件，所述第一蓄水器用于储存要被蒸发的液体，第一蓄水器与第二蓄水器之间由薄膜隔开，第二蓄水器具有与待蒸发液体接触时发生放热化学反应的试剂，而所述开口元件被启动时，会在所述薄膜上打孔，从而使所述反应试剂与待蒸发的液体接触。
在根据本发明的蒸发元件中，通过使液体本身与反应试剂(例如氧化钙)接触来加热待蒸发的液体。通过启动所述开口元件，在将待蒸发液体与所述反应试剂隔开的薄膜上开孔，从而所述所述液体与所述反应试剂发生反应并释放热，这释放的热就使得所述液体蒸发。与专利文献EP 0 371 282 A中的气溶胶蒸发装置相比，本发明的优点特别在于其更简单、更便宜、更节省空间。本发明的蒸发元件最节省空间，可以在很小的空间内以轻便方式提供能量，并通过化学方式储存和释放能量。
本发明的蒸发元件优选具有耐热、防水的外壳和安装在该外壳上、可绕铰链转动的覆盖件，所述外壳例如塑料外壳，可用聚砜或聚碳酸酯或类似物制成。
所述开口元件由例如设置在覆盖件下侧的心轴或销构成，所述覆盖件安装在所述外壳上并可转动。但本发明也可采用其它可选的开口机构，例如基于像潜水手表那样安装的旋转环的开口机构，在这种开口机构中，例如，所述心轴横向地设置在外壳内或者设置在蒸发元件上。
第二蓄水器可含有氧化钙作为反应试剂。氧化钙与待蒸发的水溶液接触后发生放热化学反应。
要被蒸发的液体可以是含有咖啡因、尼古丁和/火其它芳香物质的水溶液。
所述蒸发元件优选为嵌入在耐热且防水的外壳内，该外壳由例如金属、黏土或者最好是塑料或类似物制成。所述外壳可以具有用于蒸发液的吸入的开口，该开口例如具有可折叠通气管的形式。
具有所述外壳的蒸发元件可以非常小、结构非常易于处理，使得可将所述蒸发元件做成人们可以穿戴的便携式吸入装置，例如类似手表的手镯等。
附图说明
以下结合附图和优选实施例来对本发明作进一步详细说明，其中：
图1为根据本发明一个实施例的、不带外壳的蒸发元件的横截面图；
图2为带有外壳和关闭的盖的蒸发元件的横截面图；
图3为带有外壳和打开的盖的蒸发元件的横截面图。
具体实施方式
图1为根据本发明的一个实施例的蒸发元件的横截面图，图中蒸发元件10没有外壳。所述蒸发元件包括上部的第一蓄水器1，该第一蓄水器1作为液体贮器，用于储存要被蒸发的水溶液。本发明中的所述水溶液可以含有咖啡因、尼古丁和/火其它芳香物质。
塑料薄膜4将第一蓄水器1与第二蓄水器3隔开，该第二蓄水器3包含有反应试剂如氧化钙。优选地，第一蓄水器1和第二蓄水器3均被容纳在防水且耐热的槽5或袋子内，该袋子优选由耐热的塑料薄膜制成。
当第一蓄水器1内包含的待蒸发液体与第二蓄水器3内的反应试剂接触时，发生的化学反应产生足够的热量，使得含有芳香物质的液体蒸发或汽化。为了引发所述化学反应，必须对薄膜4进行打孔，为此，图2和3所述实施例中，在外壳的可旋转盖14的内侧设有心轴或销13。但本发明也可采用其它机构来对薄膜4进行打孔。
图2和3为带有外壳和盖14的蒸发元件的横截面图，所述盖14通过铰链12固定，因此可以转动；图2中，所述盖14关闭；图3中，所述盖14打开。
用户通过关闭所述盖14而启动蒸发操作过程，使得薄膜4被心轴13穿孔，从而引发化学反应。含有芳香物质的蒸发液通过第二薄膜2逸出，所述第二薄膜2最好由具有开口的塑料薄膜组成。但作为选择，所述第二薄膜2也可省去。上升的蒸汽通过盖14上的开口15逸出到外界。
为了使外表面绝热，本发明的蒸发元件最好具有塑料、陶瓷或其它适当材料的绝热外壳7。图2和3所示的实施例显示了具有盖14的外壳7，所述盖14具有适于吸入的开口15，该开口15处可设有软管或类似物。但所述外壳也可具有其它的形状。图中的形状仅仅只是一种示例而不构成限制。蒸发元件本身的形状除了图1～3中所示的矩形或方形之外，还可为椭圆形或类似形状。
因此，本发明提供了一种结构紧凑且便宜的、具有化学热源的液体蒸发元件，该蒸发元件占用空间小、重量轻。在本发明中，由于待蒸发液体本身与反应试剂发生反应，因此不需要像专利文献EP 0 371 282 A所述气溶胶蒸发装置中那样的额外的蓄水器。这大大降低了本发明蒸发元件的重量、外部尺寸和成本。因此所述蒸发元件也适合用于移动吸入装置，并且使用后可以很容易地予以更换，这使得本发明的蒸发元件操作起来非常便利和卫生。
